You can't see, smell, or taste radon – the only way to know is to test. We make it accurate and easy.
Radon is invisible and odorless, and South Dakota has some of the highest levels in the country. The only way to know whether your home is safe is a proper radon test – and if it's high, we can fix it.
Hardware-store kits can work, but results vary with placement and handling. Our professional-grade continuous radon monitors give you an accurate, tamper-resistant reading – and a clear report you can act on, whether you're protecting your family or closing on a home.
The EPA recommends every home be tested, and again after any major renovation. Levels run highest in winter when homes are sealed up, so January is peak testing season here. Buying or selling? A test is a standard part of the inspection – see radon inspections.
A short-term test takes as little as 48 hours. Long-term tests run 90+ days for a truer annual average.
The EPA recommends action at 4.0 pCi/L or higher. There's no completely safe level, so lower is always better – mitigation can bring most homes well below the action level.
Yes. Radon levels vary dramatically house to house based on soil, foundation, and construction – your neighbor's result tells you nothing about your home.
